A horizontal line has the equation "y = " something, while a vertical line has the equation "x = " something. If our line is horizontal through (3, 6), it will be horizontal through the y coordinate (and vertical through the x coordinate). Our equation is y = 6

(The vertical equation through this point would be x = 3, just so you understand what I meant above.)

Convert 72° 36' 45" into centesimal measurement.

zavuch27 [327]

Answer:

Answer:

Step-by-step explanation:

x= centesimal angle (100 degrees in a

right angle)

y= sexagesimal angle (90 degrees in a

right angle)

x - y = 15

xx90/100 = y

xx9/10 = y

X - XX9/10 = 15

10x/10 - 9x/10 = 15

X/10 = 15

x= 150

y = 150x9/10 = 15x9 = 135

using centesimal system:

the sum of all external angles in a

polygon is 400 degrees (a full circle).

one external angle is the complement

of one internal angle to 200 degrees =

200-150=50 degrees.

to find the number of sides of the

polygon we need to find the number of

angles or corners. and that is how many

external angles fit into the full circle.

n = 400/50 = 8

the polygon has 8 sides
